Thermal Model Verification in Interstitial Hyperthermia
In vivo tests are essential for the development and evaluation of interstitial hyperthermia systems, especially because determination of the threedimensional temperature distribution during clinical treatment is impossible: Minimal temperatures are expected to occur somewhere between the needles, requiring an extensive set of thermocouple catheters in addition to the applicator catheters. Usually the number of catheters implanted is already a compromise between the need for a small catheter spacing to ensure uniform temperatures and the wish to prevent excessive trauma to the patient. Any extra catheters available one might prefer to use for extra interstitial needles to improve temperature homogeneity. One must therefore be able to rely on the accuracy and correctness of the computed small scale temperature distribution.
